Testis, ductus deferens, and seminal vesicle histology
0 / 1 complete
The intratesticular ducts include the straight tubules (or tubuli recti), rete testis, and efferent ductules.
And the excretory gential ducts include the epididymis, ductus (or vas) deferens, and urethra.
The epididymis is a single, long convoluted duct where spermatozoa accumulate and continue to mature even further, including the development of motility.
The seminal fluid is also slightly alkaline, or basic.
Surrounding each testis is a thick capsule of connective tissue, called the tunica albuginea.
Testis, the ductus deferens, and the seminal vesicles are parts of male reproductive organs. Testes, or testis when singular, is an organ in the male reproductive system that produces sperm and male hormones. The ductus deferens is a long, muscular tube that carries sperm from the testes to the urethra. The seminal vesicle is a small organ near the base of the bladder that produces a fluid that helps to nourish and transport sperm.
Testis is composed of small, tightly packed tubes called seminiferous tubules, which produce sperm. The seminiferous tubules are lined with germ cells and Sertoli cells, which nourish and protect the germ cells. The ductus deferens is composed of smooth muscle cells and lined with a single layer of epithelial cells. The seminal vesicle is lined with a single layer of epithelial cells and is filled with secretory cells.
